If desired, for the perfect salt rim you can liquidise or grind sea salt to make it finer, then run a cut slice of lime (or orange) around the outside...
Do you really do the lime wedge garnish with this? It’s not shown in the photo and it seems a little weird dropping that into a small shallow coupe glass.
A lime wedge is not essential but adds to appearance and allows the drinker to squeeze into the cocktail if they want to make it a tad sourer. It is usually placed on the time with a slot cut into the wedge.
